when you started the activity, the can was open to the air outside tge can. how did the air pressure inside the can compare to t
aliya0001 [1]

The air pressure inside the can is lower compared to that of outside air pressure.

Explanation:

  • In general, the air pressure of an already opened can will be the same as the outside pressure.
  • Since the can is evacuated and remain as vacuum, so there will be no pressure difference in it.
  • If the can opens, air inside the can push the top and escapes to the outside.
  • This is due to high pressure experienced outside the can compare to that of lower pressure inside the can and this may even cause can to collapse itself.

A compound with chemical formula na2cx3 has formula mass 106 amu .. what is the atomic mass of element x
maria [59]

The element "X" is "O" (oxygen).

<h3>Calculation:</h3>

Given,

Chemical formula = Na₂CX₃

Formula mass = 106 amu

Molar mass of Na = 23 amu

Molar mass of C = 12 amu

To find,

Element X =?

We will equate the equation as follows,

2(23) + 12 + 3(y) = 106

46 + 12 + 3y =106

58 + 3y = 106

3y = 106 - 58

3y = 48

y = 48/3

y = 16

We know that Oxygen has molecular mass of 16. Therefore the element "X" is "O".
